Specification of Letters Patent.

Patented May 14, 1907.

Application filed August 22,1906. Serial No. 331,655.

To 0071/ whom it may concern.-

Be it known that I, MARTIN S. HEABLER, a citizen of the United States,residing at Moof Hancock and State of Ohio, have invented new and usefulImprovements in Window-Cleaners, of which the following is aspecification.

This invention relates to that class of window cleaners which areprovided with a porous strip adapted to be saturated with water or sudsfor the purpose of washing the window, and with an elastic strip ofrubber or other suitable material for the purpose of drying the window.

The object of the invention is to simplify and improve the constructionand operation of this class of devices and to provide an efficient andinexpensive window cleaner.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consistsessentially in a sheet metal blank formed with flanges for the purposeof holding the porous and elastic strips; the invention further consistsin the formation of a window cleaner from a blank of the character setforth; the invention further consists in the improved construction andnovel arrangement and combination of parts which will be hereinafterfully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawings: Figure 1 is a plan view of a window cleaner constructedin accordance with the principles of the invention. Fig. 2 is atransverse sectional view of the same taken on the plane indicated bythe line 22 in Fig. 1. Fig. 3 is a transverse sectional view showing theblank from which the cleaner is formed, said view being taken on theplane indicated by the line 3-3 in Fig. 1. Fig. 4 is a longitudinalsectional view taken on the line 44 Fig. 2.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The body of the improved window washer is manufactured from a strip ofsheet metal 1 of suitable dimensions, said strip being bent or crimpedto form two pairs of flanges 2, 2

blank are overlapped,

and 3, 3 disposed transversely of the sheet or blank parallel to eachother, each of said flanges being composed of two thicknesses of metal,as will be readily understood. The flanges 3, 3 are suitably spacedapart to accommodate between them a strip 4 of porous material, such asfelt, although other suitable material may be employed. The flanges 2, 2are suitably spaced apart to accommodate between them a strip 5 ofrubber or other suitable elastic material. The flanges 2, 2 and 3, 3 aredisposed at suitable distances from the end edges of the sheet or blankso that, when the latter is bent to the cylindrical shape clearlyindicated in Fig. 2 of the drawings, and the projecting'ends of thesheet or the flanges 2, 2 will be spaced from the flanges 3, 3 adistance varied from one quarter to one third the circumference of thecylinder. When the sheet or blank is bent to form the cylindrical body,the overlapped ends 6 and 7 are secured together by means of solder, asshown at 8, or in any other suitable manner.

When the sheet of blank has been bent to form the cylindrical body A,the flanges 2, 2 and 3, 3 will extend radially from said body.

The cylindrical body A is provided with diametrically disposed apertures9 and 10 which are connected by means of a slightly tapering tube 11;the latter being secured in position by means of solder or in any othersuitable manner, said tube being for the reception of the pole orhandle.

The porous strip 4-is secured in position between the flanges 3, 3 bymeans of transverse bolts 12 which also serve to draw said flangestogether so as to prevent them from spreading. By tightening the nuts 13on the bolts 12 the flanges 3, 3 will firmly grip or clamp the porousstrip 4, which latter projects a suitable distance beyond the edges ofthe flanges. The flexible strip 5 may be secured between the flanges 2,2 by punching or upsetting the latter to form burs 14 which engage theelastic strip so as to prevent its withdrawal. The flanges 2, 2 arepreferably reinforced upon the under side of the sheet or blank, or,which is the same thing, upon the inner side of the cylindrical body bymeans of solder, as shown at 15, for the purpose of preventing saidflanges from spreading.

A window cleaner constructed in accordance with the principles of thisinvention may be manufactured at a very moderate expense, the materialemployed being quite inexpensive while the labor required in thecomposed of a double thickness of the matemanufacture of the device isvery slight. The rial of which the cleaner is formed, a strip of porousas well as the elastic strip may be porous material secured between twoof said. readily replaced when worn. flanges by means of clamping bolts,and a 5 In using the device, it is mounted upon a strip of flexiblematerial secured between the pole or handle, it is then immersedin-water other pair of flanges by means of burs or other liquid untilthe porous strip is satuformed in one of the flanges, and a taperingrated, when it may be employed for washtube secured diametrically in thecylindrical ing awindow which is afterward dried in the body of thecleaner for the reception of the 10 usual manner by means of theflexible rubhandle.
